THlLL-COUPLING..

SPECIFICATION formingpart of Letters Patent No. 665,006, dated January1, 1901.

Application filed May 24, 1900. Serial No. 17,865. (No model.)

To all whom it may concern:

Be it known that I, DANA O. HASKELL, a citizen ofthe United States,residing at North East, in the'county of Erie and State of Pennsylvania,have invented certain new and useful Improvements in Thill-Oouplings,ofwhich the following is a specification.

This invention relates to thill-couplings, but more particularly to anantirattler therefor, and has for its object to provide an improvedsecuring means for the spring or antirattler, whereby the same canreadily and quickly be removed from and attached to the thill-iron.

With this object in view the invention consists in the peculiarcombinations and novel constructions of parts, all of which will befully described hereinafter,pointed out in the appended claims, andillustrated in the annexed drawings, in which Figure 1 represents athill-coupling constructed in accordance with myinvention and to whichthe antirattler is attached. Fig. 2 is a vertical longitudinal sectionalView of the same; and Fig. 3 is a fragmentary detail view of one of thesoon ring-nuts and the detachable end of the spring, illustrating themanner of attaching the spring in engagement with the washer.

Referring now to the drawings by reference-numerals, 1 designates theclip on the threaded shanks 2 and 3, on which is positioned the clip-bar4 and held in place by the nuts 5 and 6.

6 and 7 are the ears of the thill-iron,which pivotally carry thethill-iron 8, which is attached thereto by a coupling-pin 9. Thiscoupling-pin is provided with parallel limb 10,suspended therefrom on alower plane and which extends below the ears of the clip and the head ofthe thill-iron and is connected to said pin by a vertical bar 11 at oneend.

The antirattler 12 comprises a strip of tempered steel and isapproximately U-shaped, although one limb thereof projects beyond theother and terminates in a semicircular extension 12 and is designed toembrace the rear side of the head of the thill-iron to deaden the soundcaused by the vibration of the thill and the upper face of the nut 5,

during the motion of the vehicle to which it is attached. This spring isfulcrumed to the suspended limb of the coupling-pin bya semicircularplate 13, having a flange 14, which is riveted to the spring so that thesemicircular portion of the plate will embrace the limb 10 and normallyhold the parts together, a head 15 on the free end of the said limbpreventing the spring and coupling-pin from becoming detached. Theshorter limb 16 of the spring is carried up to a point opposite thethreaded shank 2, and its free end is then bent at right angles theretoto form a slotted extension 16 adapted to engage the tongue 17 of asquare washer 17 threaded on the shank 2 and positioned between thelower face so that when the clip is secured upon the axle of the vehicleand the nut 5 is tightened the limb 16 will be securely held against thebar 4; but said extension 16 may be sprung out of engagement with thetongue 17 by simply forcing the limb 16 toward the nut 6.

In actual practice the spring andcouplingpin will probably be put uponthe market separate and independent of the thill-coupling, as it isapplicable to many different forms of couplings and might be applied toany one of many forms now in use. I therefore would have it understoodthat I do not limit myself to the use of this device to the constructionof coupling shown, but hold that many de partures might be made from thestructure illustrated without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In a device of the character described,

of the banglethe combination With a clip and a thill-iron' adapted to beconnected thereto, of a coupling-pin connecting the two and having asuspended limb connected to one end thereof, an

antirattler-spring carried by the suspended limb of the coupling-pin,one end of which is designed to bear against the head of the thilliron,and an extension on the other end of the spring adapted to lie flushagainst the securing-bar of the clip and be secured thereto by a nut onthe shank of the clip, but so that it can be Withdrawn Without detachingthe nut from the clip.

2. An antirattler for thin-couplings, comprising a coupling-pin, havinga parallel limb connected at one end to the pin by a crossbar, anapproximately U-shaped spring fulcrnmecl to the said limb one limb ofwhich is longer than the other and terminates in a semicircularextension, and the shorter limb IO being provided with a right-angularslotted extension.

In testimony whereof I affix my signature in presence of two Witnesses.
